I know Printronics for a long time sorry to hear that you had a bad experience with them..
One question for you why going to someone who recycle from schools, churchs etc… where you could go to a real broker and get more for your empties?
Beleive me if it is what you mentione above they will take them from no matter from where you coming from. You only try to get advantage from their collection program to get money on what the real broker rejected.
Printronics is a great Company to deal with wish that was many more like them in our industry.
